- Efficient 43461
Four workers were supposed to build 200m of the fence in 15 days. However, after 3 days, two more workers came to their aid. All workers were equally efficient. Calculate how many meters of the fence (from the original 200m) remained after the first 3 day - Distance 43431
On a map at a scale of 1: 250,000, the line shows a distance of 15 km. How many cm does this line measure on the map? - Tarzan
Tarzan, weighing m = 90 kg, tries to cross the river by swinging with a vine hanging from a tree leaning over the river. Liana has a length l = 12 m. The speed of the Tarzan in the lowest swing position is v = 8 m/s. Tarzan doesn't know that the liana wil - The aluminum
We placed the aluminum object with a weight of 0.80 kg and a temperature of 250°C in the water with a weight of 1.6 kg and a temperature of 23°C. What is the system temperature after reaching equilibrium? We assume that the heat exchange occurred only bet - The bath
The bath has water with a volume of 220 l and a temperature of 65°C. Find the mass m2 of water at 15°C to be poured, so the resulting temperature in the bath will be 40°C. We neglect the heat exchange between water and the environment. The mass
